feat: introduce mode config option

[LukasHirt]

Description

Introduce new config option to assert in which mode the UI should be rendered. There are two ways to set the mode, either by adding it into the options object in the config or via mode query param. The config option takes precedence when both are defined. To showcase the functionality of the config, hide elements in the embed mode in the top bar component.

Motivation and Context

This is needed to have functioning embed mode. Providing both config and query approaches makes us future proof. Same applies to having the option as mode?: string instead of e.g. embedded?: boolean so that any other mode could be introduced in the future...

How Has This Been Tested?

• test environment: local dev env
• test case 1: open https://localhost:9200?mode=embed
• test case 2: set options.mode to embed in config.json - does not work because of custom config not working (but unit tests are passing)

test case 2: set options.mode to embed in config.json

Does this work for you without setting the query param? Normally it shouldn't because the config is still missing in oCIS 🤔

Strange... I tried it once and it worked. I must have screwed up somehow my local env. Trying it again does not work indeed.

Anyway, I guess we can merge this still? The unit test for the config value is passing so once config is working in oCIS - it should work 🤷
